CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 259,948, dated June 20,1882. Application filed January 27, 1882. (No model.) Patented in CanadaOctober 19, .1881, No. 13,566.

1 0 all whom it may concern Be it known that I, LoUIs HoNoRE TOUR-VILLE, a subject of the Queen of Great Britain, formerly residing at St.Henri, Province of Quebec, Dominionof Canada, but now of Ohicago, in thecounty of Cook, State of Illinois, have invented certain new and usefulImprovements in Gar-Axle Boxes; and, I do hereby declare the followingto be a-full,clear, and exact description of the same, sufficient toenable others skilled in the art to make, construct, and use the saidimprovements or invention.

The objects of the invention are, first, to improve the lubrication ofcar-axle journals, so as to avoid the use of cotton waste or otherpacking, and the consequent danger from the ignition of such packing;second, to check the entrance of dust, grit, 850., into and against thejournal-bearings, and as Well to check the escape of lubricant onto thetrucks or parts of the car contiguous to the journal.

To these ends my invention consists of certain improvements in thestructure of car-axle boxes, substantially as hereinafter set forth, andparticularly defined in claims.

Referring to the drawings which accompany and form a part of thisschedule, and wherein like letters of reference denote like parts,Figure 1 shows a longitudinal section of axle-box and journal on lines'o w of Fig. 2, a portion of p the lubricating-roll and its bearingbeing in elevation. Fig. 2 shows a transverse section of the axle-boxwith journal and lubricatingcylinder removed, the movablejournal-bearing for the latter being. somewhat elevated from its seatand the check-plate in part broken away to show its interior structure.

Within the usual box or casing, A, and resting on its bottom plate, isan ugright removable frame consisting of two curvilinear end plates, BB, which are firmly joined together at opposite points by the side rods,j j, said rods being screw-threaded. and provided at one end withset-nuts a a, whereby the several parts may be securely held or takenapart, as desired.

Attached to'or made in piece with theplates B B, and at each lowercorner thereof, is an enlarged tubular standard or leg, I), whichrece'ives within its cylindrical cavity a coiled I spring, 8, and aswell a cup-like rest or support, 0, that encompasses said spring and isfree to slide within the tubular leg. By this arrangement the entireframe rests primarily 5 upon the springs s, and'so is adapted to yieldto any irregularities of pressure, while the springs, being retainedwithin the tubular legs I) and cups 0, are not displaced by any suddenmovement or jar to which the frame may be subjected.

0n the inner face of each of the end plates,

B B, seats or recesses are formed, having dovetail edges and shoulderswherein fit and rest corresponding parts of the removable side 6 5pieces, 6, and central section-piece, a, said central piece beingsuitably perforated-to receive the journal of the lubricating cylinderor roll 0, and as well provided with the projection to afford a betterbearing for the journal aforesaid. It is manifest that in making theseseveral pieces (brasses) removable they can be readily replaced whenbroken or worn, and that the lubricatingroll can 'be reversed end forend or a new one substituted at will.

The lubricating-roll 0 consists preferably of a series of rings, 9 g, offelt, leather, clothtufted carpet, vulcanized fiber, or the like,arranged transversely upon the axle-rod h, and firmly clamped togetherbetween the retainingplates 2' t, the screw-threaded perforations ofwhich engage with like threaded portions of the rod h. A series ofspiral grooves, k 70, is cut peripherally on the edges of the rings toaid in elevating the lubricant inwhich roll 0 is immersed, ashereinafter described.

Through an opening in the upper part of the casing A is inserted arectangular checkplate,'D, the lower edge of which rests on the bottomof the box, said check plate being 0 transversely perforated, so as toallow for the free passage of the car-axle journal, which latter, whenin position, fits snugly to the under curve of the perforation in thecheck-plate, while within the box said journal, substan- 5 tiallythroughout its length, bears lightly upon the face of thelubricating-roll O, the springs s in the legs of the frames being of thetension requisite to insure such contact. The upper portion of thecheck-plate D is recessed or hollowed out to receive a slide, 1, fittedwith a leather or like strip, 1, of which the lower edge is curved toconform closely to the journal E. Springs m on the stems m bear againstthe slide 1 and the under side of the closed top of the check-plate, andso force the strip Z into close contact with the journal.

Two hand-rods, n n, attached to the slide l and projecting through theclosed top of the check -plate, allow for the temporary withdrawal ofthe slide and attached strip within the recess whenever it is desired toremove the journal E from its position in the box.

A plate, 0, rectangularly recessed to admit the check-plate D, restsupon the top of the box or casing A and sustains a spring, 1), which ishoused within an inverted cup, q, made rigid with the closed top of thecheckplate by means of the bent strap 1'. The recoil of said spring 19tends manifestly to lift the check-plate D, and in consequence keeps thelower curve of the perforation in said plate close against the journalE.

It is plain that by the construction of the several parts as described atight joint is formed entirely around the journal, so that dust cannotenter nor the lubricant escape from the box, and yet the axle be free toadjust itself to sudden jars or strains.

The several parts being constructed and arranged as heretoforedescribed, a quantity of oil or like lubricant is poured into the box Auntil the lubricating-r0110 is about one-half submerged. It follows,then, that any rotation of the journal E causes corresponding rotationof the roll 0, with which it is in contact, so that fresh portions ofthe lubricant, in the nature of a thin film, are being constantlyelevated from the bottom of the box and distributed upon the journalover substantially the length in contact with the brass, such actioncontinuing until the journal ceases to rotate or the lubricant falls solow as to no longer submerge the roll. The need of cotton waste or oflike packing is avoided, the lubricant is used with minimum loss and isefiectively distributed, the necessity ofrefilling the box can beascertained upon quick inspection, and there is practically no chancefor a destructive heating of journal brasses or box, which the ignitionof the cotton waste in the old forms of box was very apt to cause. Whenthe rings 9 g of the roll 0 become worn they may be readily replaced,and by adjustment of the retainingplates i i the rings can, withinlimits, be compressed into contact with the journal E. The check-plate Deffectually excludes the dust, grit, &c., so that there is nodestructive cutting of brasses orjournal, and as well prevents theescape oflubricant, which, in the ordinary axlebox, causes unsightlystains upon the trucks, the frame-work, and the axle-boxes.

I am aware that it is not broadly new to set brieating-roll, as in theinvention hereinbefore v detailed.

I am aware that check-plates have been used in connection with car-axleboxes to exclude dust and retain oil; but in these the plate hasgenerally been made of upper and lower sections to encompass the axle,and not entire, as in my device, nor with an interior slide, nor yetwith an outer plate resting upon the caraxle box, whereby, incombination with the check-plate, the latter may be held snugly againstthe axle.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. In a car-axle box, a removable frame to sustain the lubricating-roll,said frame having recessed end plates and separable sectionpieces whichdirectly fit and fill the recesses and support the journals of the roll,substantially as described.

2. In a car-axle box, a removable frame to sustain the lubricating-roll,said frame having recessed end plates and separable centralsection-pieces, e, and side pieces, 0, which directly fit and fill therecesses, substantially as set forth.

3. In a car-axle box, the combination, with the recessed check-plate, ofa movable slide located within the recess and adapted to bear againstthe body of the car-axle, substantially as described.

4. In a car-axle box, the combination of the recessed check-plate D withthe movable slide Z, located within the recess and provided with therods a n, substantially as set forth.

5. In a car-axle box, the combination, with the check-plate D, made inmanner substantially as described, of the recessed plate 0, which restsupon the exterior of the box, and the sustaining-springp, allsubstantially as set forth.

6. In a car-axle box, the combination, with the check-plate D, slide l,and spring m, of the plate 0 and spring 12, substantially as set forth.

In witness whereof I have hereunto set my hand this 19th day of January,A. D. 1882.
